The effects of SNPs on PSA level (ng/mL) in men with PSA3-10ng/mL and a diagnosis of prostate cancer.

CI = confidence interval.a Additive model, calculated using regression, adjusting for exact age, study centre and 10 principal components to account for confounding by population stratification.b F-statistic and R-squared (R2) indicate how much of the variability in PSA levels is explained by each SNP. Calculated using regression, unadjustedThe effects of SNPs on PSA level (ng/mL) in men with PSA3-10ng/mL and a diagnosis of prostate cancer.

CI为置信区间（confidence interval）。
a 加性模型：通过回归分析计算所得，校正了精确年龄、研究中心以及10个主成分，以控制人群分层带来的混杂偏倚。
b F统计量与决定系数（R²）用于反映每个单核苷酸多态性（Single Nucleotide Polymorphism, SNP）对前列腺特异性抗原（Prostate-Specific Antigen, PSA）水平变异的解释程度，其通过未校正混杂因素的回归分析计算得到。
本数据集聚焦于PSA水平介于3~10ng/mL且确诊前列腺癌的男性群体，探究了单核苷酸多态性（SNP）对PSA水平（单位：ng/mL）的影响。
